Type P133 Gas Pressure Reducing Regulator

The BelGAS Type P133 gas pressure reducing regulator is used in commercial and industrial applications such as furnace and burners, where accuracy and sensitivity are critical.

Offered with a wide range of pressure capabilities within a single regulator, from 2” of water column up to 10 psig, the compact BelGAS Type P133 reduces the effects of supply pressure changes on output pressure via a balanced diaphragm design for accurate control.  With user selection of appropriate options, the regulator can be further utilized in either low- or high-pressure applications. Units are designed to reliably operate over a temperature range of -20° to +150°F (-29° to +66°C).

In addition, the bubble-tight shut-off feature makes the Type P133 ideal for use with residential and light industrial heaters and industrial burners, as a reliable means of supplying gas to furnaces, burners, light industrial heaters and other appliances. No seat-to-seat adjustment is required.
